Airs Sunday, December 18, at 6 p.m. Unable to speak until age four and diagnosed autistic in the 1950s, Temple Grandin went on to defy expectations, becoming a renowned author, activist and expert in humane livestock design. Honing her ability to see and think differently, this self-described “anthropologist on Mars” has brought enlightenment to her field and a new understanding of autism to the world. David D’Arcy hosts this journey into a truly Independent Mind. Temple Grandin’s own voice guides this Independent Minds radio hour.
